I To all lwhom 'it may concern Be it known that I, WILLIAM EARL RUS- SELL, a citizen of theUnited States,res`iding in the city of Danbury, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Circuitj Closers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'I his invention relates to certain new and usefulimprovements in circuit closers, and relates. more particularly to circuit closgs of the type employed in connection with door bells, elevatorl signals, andthe like, operated by highvoltage currents.

The primary object of the invention is to provide a circuit closer'whichI elects lightcontact members being omitted; Fig. 3 is 4a 1 side' elevation; Fig. 4 is alside elevation partly broken away and in section illustrat- 1ng the parts in position to close the circuit;

Fig. 5is a top plan view of a modified form of the inventionl for use with double pole circuits; Fig. 6 is a side elevation of Fig. 5; Fig. 7 is a similar view showing ythe parts in position to close the circuit; Fig. 8 1s a detail view showing the reciprocal 'device in .v

end elevation; and Fig. 9isza detail perspective view of the inner frame. .h

insulation 3 being interposed between the base and terminals. Contact members 4 into the slots 16.

Rilidly secured to the base' 1 is ai-frane which has a paiiof spaced parallel arms 6 and a perforated upwardly extending guide member 7 located 1n spaced relation to the arms 6. The contact member 8 is of substantially U-shape and has oscillatory movement, the free ends of its legs being pivoted by means of pins 9 or the like to the arms 6 to enable the member 8 to be moved from theubreak position shown in Fig. 3 to the make or operative position shown in Fig. l4.

The endlO of the member 8 is provided;

with a perforation 11 through which-passes the free end of a rod; 12, which rod has a head V13 at its inner end, a coil spring 14 surrounding the rod 12 and having its 'ends abutting the head 13 land the end 10 of the member 8. The head 1 3 ofthe rod 12 is .pivotally mounted on a pin 15 which latter has vertical reciprocatory movement in the .vertical slots 16 formed in the vertical spaced parallel arms 1,7 of an inner .U-

shaped frame 18 which latter is attached to.

The slots 16 the base of the main frame l.

preferably having 'right angular entrances f 16 to enable the in 15 to be introduced passed through the perforation of guide ymember 7 and basa head/20 on its inner end, which is also pivotally mounted on the pin 15, a spring 21 surrounding ,the rod 19 and abutting the guide member 7 and head 20 at itsen.

A reciprocal actuator, shown by way of rod 19 has its free end example as a pushbutton 22' has a pair of spaced arms 23 secured thereto, which yarms are perforated to receive the ends of the pin 15, the latter having a central enlargement 24 which, contacting with the inner faces of the arms 23, holds the arms 23 in spaced relation.

In Voperation inward movement of the arms 23, accomplished in thepresent disclosure by depression of the button 22, will cause the pin 15 to move toward the base @1,

1- thel pin moving along the length of the slots l16, until the pin 15 passesthe pivotal points 9` of the contact member 8, and at the mo- -ment of passing, the r'od 12'wil1 have its seat on and are secured to the blocks 3 and v are. disposed beneath the terminals 2, and

have electrical contact with said terminals,

thev contact members 4 having lips 5 whilch re a-` extend towa'rd each kother 1n spaced tion and which rovide stops that limit the rd) movement ofthe swinging contact member 8.

head 13 moved to ,lowered position, below I the pivots 9, thus causing the spring 14,

which 'has'been compressed, to move the contact member 8 with great Vrapidity from the position shown in Fig'. 3 to that shown in Fig. 4. As soon as, the 4button 22 is released, the spring 21 which has also been compressed by the stated movement of the pin 15, 'will exert pressure on the pin 15 and A.

the wall which the opening, formed to receive said button, provides.

From the above it will be apparent that two independent springs are utilized, one being for the purpose ofmoving the swinging contact member with great rapidity to closed or make position and the other for the purpose of returning the swinging contact member to open or break position.

In the form of the invention shown in Figs. 5, 6 and 7, a double pole type of switch or circuit closer is disclosed, which differs from the aforedescribed form of the invention in the following respects:

The lever 8 which operates' and is constructed identical with the contact member S of the single pole type is not employed as a contact member, though carrying and used to actuate a pair of contact arms 25 which latter at each of their ends have spring fingers 26 which receive 'the knife-edge terr.

lminals'27. The lever '8' is pivoted to the arms 6 of the main frameby meansiof studs 28, which studs arerigidly secured by means of screws 29 tohubs 30 which are secured to the arms of the lever 8 whereby movement of the lever effects movement of r the studs therewith. L/The outer ends of lthe studs 28.are formed with heads 31 to which clamping plates 32 are' connected by means of rivets 33, or the like, the plates 32 engagg the contact arms 25 and the latter in urn engaging insulation 34:.whi'ch abuts the heads" 31. In order to limit the upward movement of the contact arms afstop 35 is secured to one Aof the arms 17 vof the inner frame 18. l

-It is particularly'to be note that upon depressiqnrof the push button 2 that power is stored in the springs 14 and 21, and upon' `continued movement of the push button, the

l power inthe spring '14 is enabled to move the member 10 .to make position, with great v rap1d1ty, s1nce the inner end of the rod 12.

has been moved' in a plane below that in whichthepivotal points 9 of member 10 lie. Also, when the .push button 'is forced inwardly, the independent pivot pin 15 is arrested byl the walls at the inner ends of the' slots 16, and, on the reverse movement of sald button, said pin is arrested by the walls at the outer ends of said slots, this operation yet-the pivot pin 15 between prescribed limits belng obviously for the purpose of -preventing any` oyerthrow of such pin in either direction. It will be noted that thepush button ,is

15, which renders the operation of my device exceedingly easy, requiring as it does a minimum of force to effect the reciprocal movements of said pin. Y

I 'Vhat is claimed is:

'1L In a circuit closer, a pivoted contact member, a pair of independent springs connected to said member and means to actuate the springs to cause one of same to :move said member to make position and the other to move Isaid member to break position.

2. In a circuit closer, a pivoted contact member, a pair of rods one of which has sliding engagement with said member, means to guide the other rod, a pin to which each rod is pivoted,'means to allow sliding movement of the pin, means'to actuate the pin to slide same, and springs surrounding the rods and engaged with said member and said guiding means respectively. `3. In a circuit closer, a. pivoted lever for closing and opening a circuit, an' element capable of reciprocations in ya plane coincident' with the 'plane in which said lever swings from its pivotal point, said element in its reciprocations passingthe pivoted point of said lever in both directions, spring actuated devices carried by said element` and,

operating to throw .said lever to make and break positions when said element is reciprocated, and manually operatedmeans for forcing said element inwardly against the y resiliency of said springs, the latter operating to restore the parts to normal position.

4. A circuit closer, comprising a pivoted make and break element, a pair of angularly in said element, springs associat d with'said members to retain them in thei normal positions, and manually operated means for forcing the 'pivotal point of said members A to 4a plane within the plane of the vpivotal point of said element and against the 'I" esiliA ency of said springs, whereby the partial recovery of the latter will immediately 'throw said-element to close a circuit, while thel complete recovery of said springs will restore said element to normal posltion to open a circuit immediately on the release ofA sa 1d means. l

In testimony whereof I .aiiix my signature l in presence of two witnesses.
